But did you know that from Emacs 28.1 there's a customizable variable for that? Now you just need to set "use-short-answers" to "t". Or use the Custom interface.</p><p><a href="https://hostux.social/tags/Emacs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Emacs</span></a></p>

Recently discovered a highlight feature of emacs, which makes it dead simple to change the face for a particular text. Check M-s h C-h, also take a look at hi-lock.el.
Thanks to Bhaskar Chowdhury.
When editing a file in Emacs `C-h S` allows to see the documentation for symbol at point or other item relevant to major mode (can be typed in minibuffer prompt).
For Texinfo files it will be searching entries in Texinfo manual, for shell files it will look up Bash, gawk, sed, coreutils, diff info pages.
This behavior is controlled by info-lookup-alist variable. Learn more with `C-h v info-lookup-alist RET`.
If I have a sudo or other interactive command in a Makefile I run compile/project-compile with universal argument to make Emacs prompt for interactive shell input.
C-u M-x compile
M-x recompile
Did you know that you can navigate magit status buffer elements with imenu?
consult-imenu in my case.
